- What is the importance of using P&ID for process engineering?
I currently work at Georgia Pacific in wood products, we make OSB. I have worked as an electrician on shift for several years which meant that there were several times that I would have to troubleshoot and identify issues on my own because I was the only electrician in the entire mill most of the time. I used P&ID’s a lot during this time and it helped me with comparing I/O in the PLC to the actual field devices. The P&ID would point me exactly to where the field device was that I was having the issue with. P&ID’s can also be used to understand the flow of the process as well; identifying gas trains, induced draft systems and more.
- Elaborate on the history and development of the ISA standard 5.7 and discuss examples of P&ID uses.
The ISA standard’s main focus upon its creation was to create a set of recorded documents that can be shared on a national basis. ISA5.7 is the development and use of process flow diagrams and P&ID’s.
